Phrases are mostly built from Utterances (Utt), which in turn are declarative sentences,<br />

questions, or imperatives - but there are also ”one-word utterances” consisting<br />

of noun phrases or other subsentential phrases. Some Phrases are atomic, for<br />

instance ”yes” and ”no”. Here are some examples of Phrases.<br />

yes<br />

come on, John<br />

but John walks<br />

give me the stick please<br />

don’t you know that he is sleeping<br />

a glass of wine<br />

a glass of wine please<br />

There is no connection between the punctuation marks and the types of utterances.<br />

This reflects the fact that the punctuation mark in a real text is selected as a<br />

function of the speech act rather than the grammatical form of an utterance. The<br />

following text is thus well-formed.<br />

John walks. John walks? John walks!<br />

What is the difference between Phrase and Utterance? Just technical: a Phrase is<br />

an Utterance with an optional leading conjunction (”but”) and an optional tailing<br />

vocative (”John”, ”please”).<br />

2.2 Sentences and clauses<br />

The richest of the categories below Utterance is S, Sentence. A Sentence is formed<br />

from a Clause (Cl), by fixing its Tense, Anteriority, and Polarity. For example, each<br />

of the following strings has a distinct syntax tree in the category Sentence:<br />

John walks<br />

John doesn’t walk<br />

John walked<br />

John didn’t walk<br />

John has walked<br />

John hasn’t walked<br />

John will walk<br />

John won’t walk<br />

...<br />

whereas in the category Clause all of them are just different forms of the same tree.<br />

The difference between Sentence and Clause is thus also rather technical. It may<br />

not correspond exactly to any standard usage of the terms ”sentence” and ”clause”.<br />

Fig.3 shows a type-annotated syntax tree of the Text ”John walks.” and gives<br />

an overview of the structural levels.<br />

Here are some examples of the results of changing constructors.<br />

1. TFullStop -> TQuestMark John walks?<br />

3. NoPConj -> but_PConj But John walks.<br />

6. TPres -> TPast John walked.<br />

7. ASimul -> AAnter John has walked.<br />

8. PPos -> PNeg John doesn’t walk.<br />

11. john_PN -> mary_PN Mary walks.<br />

13. walk_V -> sleep_V John sleeps.<br />

14. NoVoc -> please_Voc John sleeps please.<br />
